From 8f5fef2c78b95de1a636ce27111722b71702212a Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Mon, 21 Dec 2020 08:29:34 +0000 Subject: ip: Path MTU Type: feature Support setting the MTU for a peer on an interface. The minimum value of the path and interface MTU is used at forwarding time. the path MTU is specified for a given peer, by address and table-ID. In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.
